The AirTAC GC600-20G AirTAC F.R.L. Combination, G3/4, Low-Pressure is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT3/4" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600-20G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is size 600 with a G3/4 (BSPP) port, the 40 um standard filter element, a differential-pressure drain on the filter bowl, and the low-pressure type regulator for applications that set below the standard range. It carries a fitted round gauge reading in psi, a reverse/check valve on the regulator, and a mounting bracket. At size 600 the filter bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, with port options, drain types, 5 um (W) filtration, gauge styles and scales, and G or NPT threads available as order options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet numbers for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF600-20 filter, GR600-20 regulator and GL600-20 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Feeds filtered, regulated and lubricated air to spray guns and atomizing air headers on a paint line, where the low-pressure regulator type and clean, oil-misted air support consistent finish work.
Supplies treated air to carton formers, seaming heads and actuated grippers on a packaging line, with the psi gauge giving operators a familiar local reading at the set point.
Conditions the air feeding clamps, vises and tool-change cylinders on a CNC cell, so the reverse/check valve helps hold the regulated circuit and the lubricator keeps actuation seals working.
Step up or down through the GC sizes (200/300/400/600) to match the port and the flow your line needs; this unit is the size 600, G3/4 step. Drain choice on the filter is differential-pressure (default, as here), automatic or manual. Filtration is 40 um standard; specify 5 um (code W) where finer cleaning matters. The regulator in this code is the low-pressure type, so confirm your set pressure with us before ordering. Gauge options are the embedded square gauge or an external round gauge (as fitted here) with MPa, psi or bar scales; this one reads psi. Thread is G (BSPP) on this model, with PT as the catalogue standard and G/NPT as order options. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before you order.
Quick checklist
The aluminium-alloy bowls on the GC600 suit harsher environments than PC bowls. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR600-20 regulator with a GF600-20 filter on that branch.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the flow and datasheet figures for the GC600-20G on request before you order.
The L in the code marks the low-pressure regulator type, intended for set points below the standard range. Its exact adjustment range is not published in the data we hold, so confirm your required set pressure with us and we will verify suitability on request.
